Excellent purchase
I was a little concerned after reading older reviews about packaging. This arrived with form fitting foam around the battery. It has no damage, it arrived fully charged and ready to use. This is my third optima battery. The one I replaced lasted 12 years. I love these batteries.

Work Well
Use these (2) on my boat to power my iPilot trolling motor...so far they keep powered up throughout the day. Keep them on a trickle charge for ASM batteries and they are ready to go for each trip. An overnight charge does the trick for quick turn arounds.

they always perform better than other batteries
I've used Optima Batteries for some time, they always perform better than other batteries. Some of the Optima's that we use every Spring are a bit over seven years old, they still function perfectly. It important that you use a battery tender and never let any battery fully discharge.

Worth every penny
This was not my first purchase of this item. I had two previously and have used them for multiple purposes. Right now my latest purchase of this item is serving as the auxiliary battery in my camper van, charged by either the vehicle's alternator (with a sweet isolator setup so my starter battery doesn't ever drain from various camper component draw, and also the aux battery charges via alternator while the engine is running). I also have this battery connected to a solar charging system in my camper van, and it performs fantastically. I have actually purchased a second BlueTop to provide more power in my vehicle while I'm camped and running various lights, devices chargers, and other electrical components without the engine running. No question, Optima is not messing around. They make incredible batteries that absolutely live up to the claims made on their website. They even provide instructions on how to restore a "dead" battery after years of use and extreme discharge. That says a lot. Bottom line: you get what you pay for!

Very good battery
I broke down and spent the $ for this battery after going through more than a few lead-acid type batteries. Conditions in the desert where I live is hard on batteries. In retrospect this would have been a better choice and cheaper in the long run. My RV stays parked much of the time but now I don't have to worry about the battery when I take it out. It works great and has a lot of power. It runs down and completely recharges over and over. I guess you get what you pay for...

Works perfect!!!! Heid up all day
Much lighter than a walmart battery so far so good, we will see if it holds up with a all day fish, I will update later Upadate 4/20/16 Used this 8 hours on a 52 lb minn kota, It was windy and I used it hard hard figured it would go down before I left the lake, I was afraid it would not start my 25 hp motor, At end of day my trolling motor has a gage to check battery reserve and it said 3/4 full is that impossible so I had another battery checker and it checked 3/4 full can that be true, can that light of a battery hold that kind of reserve, If this is true and I guess it is,this is the only battery I will ever have. Finally something that gets me thought the day and I can carry from the boat that does not weigh a ton, I will update if things change. Update 5/3/16. Ok had it out 11 hours used hard hard, showed 12.2 volts, check with meter showed 1/2 charge left, unbelievable only battery I will own know matter the cost. Will update after a year 5/1/17 Ok bought a bigger boat with a older foot controlled trolling motor, the battery. We fished and used it from 9:00 am until 8:00 a 11 hour day of pretty much nonstop. After about 11 hours battery died. I still am very happy, if I had to do it over I would of bought the D31M check it out. It has 75 ah. That would have enough to run the day. Just a thought. It not that much more to buy the 31. My friend has a 31 and has had it for years maybe 6 or 7. Still works perfect.

Power that lasts
Expensive yes, but they work so well. I put 2 in my RV connected to 4 solar panels, a controller, and inverter. They are smaller and lighter than the Deep Cycle batteries that came out yet have more amp hours and will last many years longer.

Nice but a little pricey
These are great but pricey. I replaced my boats 2 batteries and along with some fresh cables and a connection for a solar charger with these. They're raw voltage stays in the high 13's and I'm reading 14.3 when the engine is running. Certainly starts the boat right up. No need to worry about acid spills and corrosion (I sprayed the finished connections/posts with a couple of heavy coats of Boeshield). Running the tilt/trip to raise or lower the engine when it's off doesn't even show a voltage loss. Anyway, plenty of power, rated for deep cycle and starting.

Long life Battery
This is my second Optima battery. The first lasted over 10 years in my 4WD toyota truck. Ran in temperatures from -30c to 40c. I look forward to this one performing as well in my trailer. So far so good

Sturdy Package
Arrived today (2 days) in a very sturdy cardboard enclosure. I was a little worried about the packaging based on some reviews but it looks like they got the message. I anticipate the Optima product will be as reliable as all the other Optima batteries I have had over the years. I highly recommend this product and purchase method.
